UEYTE CLARENCE H. GONANT, CHICAGO, ILLINOIS ELEGTRICAL CONNECT'ER Application filed June 18, 1926. SerialNo. 116,986.

lhis invention relates to connecters of the type employed for telephone and telegraph lines, and has for its object to provide an insulator which virtually eliminates dissipation of the current to the equipment supporting the conductor. I

,A further object of the invention is to so construct the insulator that an internal dry spot will be had which is proof to rain,dust and other disturbing influences.

A still further object of the novel insulator is to also construct the same as a connec- I ter for the handy separation or connection of the conductor in the event of a test or repair.

A final but nevertheless important object of the invention is to construct the same of few and simple parts, whereby it may be produced and installed at low expense.

With the above objects in View, and any others which may suggest themselves from the specification and claims to follow, a better understanding of the invention may be gained by reference to the accompanying Fig. '4: is a section on the line 4r-h of Figure 3, and

Fig. 5 1s a perspective view of a detail.

tor in which the novel insulator is interposed,

these being embedded and soldered into ter forms a bottom closure for the latter except that the rim or bottom wall of the housing isspaced from the periphery of the disk to facilitate the drainingof water from the housing when it rains or snows. f

To maintain the terminals 11 and 12 in engaged relation, they are fitted with'means which co-operate to actas a locking retainer. Thus, theterminal 12 terminates with a short neck 12?) which is usedas a support for a jack 15, the latter being perforated and pressed upon the neckof the terminal; The jack has medial and terminal flanges 15a. and 156 which are apertured at 150 to permit the passage of the plug 11a of the terminal 11, and the apertures have alined' extensions 15d to clear a side lug 11?) of the terminal plug 11a. The base of the plug 11a is coni-, cally enlarged as indicated at 110 to meet the stock of the terminal 11; and the apertures 150 are somewhat out of alinement.

When the terminal 11 isadvanced with its plug in the direction of the jack 15, the plug may be inserted like a hey, its rounded tip forcing the jack to warp somewhat, owing to the misalinement of the apertures 15c, and therefore'to firmly grip the plug; also, when the plug has been fully advanced, its conical base 110 snugly seats in the lower aperture 150, makingagood electrical contact with the jack. The side lug 11b is now above the medial flange 15a of the clip 15, and a twist of the terminal 11 causes the lug to depart from the site ofthe aperture exte'nsions15d, Referring specifically to the drawing, 10 denotes the sections of an electrical conducand locks theterminals in engaged relation. Thedeparture of the lug occasions the travel thereof over a rise 156 into apocket 157', these elements being pressed from the medial flange 15a of the jack. The pocket aifords the lug a seat and prevents the return of the lug to disengaging position from vibration or shock.

I The insulator also incorporates .a safety drain agalnst excess current load. In the housing 18 is embedded a copper ring'16,

which spacedly surrounds the terminal 12 and the jack 15, tapping off with a conductor 17 to'the ground. NVhen the line is overloaded or heavily charged by atmospheric conditions, the excess will jump the gap between the terminal and the ring and leak off to the ground.

An appliance is thus had which functions as an insulator, a connecter, and an overvoltage relief, all in a small and compact article approximating the size indicated in the drawing. The construction of the housing assures the security of the dry spot within, the method of fitting the plugs provides an intimate and dependable electrical connection, and the spaced ring furnishes a ready relief in the event of an overcharge. The device is simple and rugged, and is capable of being produced at low cost.

lVhile the drawing illustrates the preferred embodiment of the invention, it is possible that various changes and refinements may bemade therein, and it is understood that I intend to include such changes and refinements as coming within the scope and spirit of the appended claims.

I claim 1. A connecter comprising a bellhousing of insulation having a rim, a terminal carried by the housing, a bottom closure for the latter and spaced from the rim thereof, a plug carried by the closure, a yieldable jack for the plug carried by the terminal, and means to lock the plug in the jack, said jack having sections containing slightly staggered plug-receiving perforations conducive I to tension of the jack upon the plug.

2. A connector comprising a housing formed of insulating material, a terminal member embedded therein, a substantially tubular jack carried by and extending from said terminal member within the housing, spaced sections carried by said jack and extending laterally from the walls thereof and provided with key-hole slots therethrough with the slot in one section being slightly out of registry with the slot of another section, a contact plug for insertion in said terminal member through the slots of said jack sections whereby to distort said sections for biting contact with said plug, a locking lug on said plug and insertible through said keyhole slots, said plug being rotatable after insertion to dispose said lug over the face of one of said sections, and cooperative means on said plug and jack for locking said plug in position in said terminal.

3. A connector comprising a housing of hell shaped insulating material with an open bottom, a terminal jack embedded in said housing and extending thereinto in spaced relation from the walls thereof, a contact plug insertible in said housing and jack, means for lockin said plug in inserted position, said housing having an internal shoulder of reduced diameter surrounding said jack in spaced relation adjacent and inwardly of the housing bottom, and a closure member carried by said plug for seating against said shoulder in spaced relation to the bottom wall of said housing.

In testimony whereof I aflix my signature.
